Whats New with Circular 230?

The IRS made revisions to Circular 230 recently. Circular 230 is the Treasury Department’s collection of regulations governing tax practitioners. Apparently it now includes information relating to the new return preparer oversight program. It also includes “other changes.” Might have been nice if the IRS had highlighted the changes. Do I need to hire an intern to go line by line comparing the old version with the new one?
